STEVEN RADIMAK, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO DAVID SCHIFFER, OF NEW YORK, N. Y.

MAGAZINE BRUSH.

Application filed. November 4, 1922. Serial No. 599,113.

To all whom it may concern:

Be it known that I, STEVEN RADIMAK, a citizen of Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Magazine Brushes, of which the following is a specification.

This invention relates to liquid applying brushes such as are used in painting whitewashing, shoe polishing or the like, having more particular reference to a brush provided with a receptacle or magazine from which the liquid is fed, as used, to the bristles.

The invention has for an object to provide an efficient brush of this type which is inexpensive to manufacture and is easily handled.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a side view of a paint brush embodying my invention.

Fig. 2 is a transverse vertical section on the line 22 of Fig. 3.

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1.

Fig. 4 is a side view showing the invention embodied in a shoe blacking brush.

In constructing my improved brush I pro vide a hollow casing in which is a follower 11 from which a stem 12 extends rearwardly through the casing, being guided by a U-frame 13 having outturned feet 14 fixed to the rear end of the casing, the stem 12 having a hooked handle 15 on its rear end.

The follower 11 is urged forwardly in the casing 10 by a coiled expansion. spring 17 coiled around the stem 12 in said casing behind said follower and may be held in retracted position by a catch formed by a tooth 18 on a flat spring 19 secured at one end to the frame 13, the tooth 18 being adapted to engage in one of a number of ratchet serrations 20 in the stem 12. Forward movement of the follower 11 may be limited by a lug 21 on the stem 12 engaging a cross-piece 22 in the frame 13. w

The casing 10 has a head 25 mounted in its forward end in which the bristles 26 are fixed, this head having a series of apertures 27 therein with which communicate tubes 28 leading outward among the bristles. These apertures 27 are controlled by a valve in the form of an elongated plate 29 slidable on the head 25 and having a stem 30 project ing through a boss 31 on the casing 10. The outer end of this stem 30 has a swivel engagement, as indicated at 32, with a cap 33 screwed on the boss. By turning this cap 33 the plate 29 is moved to expose greater or lesser portions of the apertures 27 and so control the flow of the paint to the bristles 26. A suitable filling opening, closed by a screw-threaded plug 35 is provided in the casing 10.

To control the pressure of the follower 11 against the paint in the casing 10 the frame 13 has hinged thereto as at 40 an arm 41 having on one end a brake-shoe 42 adapted to bear on the stem 12 the opposite end of the arm 41 being in the form of an extended thumb-piece 43. A. spring 44 is fixed to the frame 13 and bears outwardly on this thumb-piece 43, thus pressing the brakeshoe 42 against the stem 12. By exerting greater or lesser pressure on the thumb-piece 43, while the brush is being manipulated, the painter can control the pressure of the follower 11 on the paint and so regulate the flow thereof. It will be understood of course that a catch such as shown in Fig. 1 may be provided to hold the follower retracted.

In Fig. 5 I have shown the invention applied to a shoe-brush, the casing being indicated at 10 and having a laterally extended handle fixed thereto. The follower 11 has a stem 12 guided by a shorter U-frame 51, the follower being held in retracted position by a hinged latch 52 engaging a ratchet notch in the stem. Forward movement of the follower maybe limited by a pin 54 on the stem 12 engaging the rear end of the frame 51.

The bristles 26 are fixed in a head 25 having a series of apertures therethrough from which tubes 28' extend forward among the bristles. The control valve is in the form of a flanged disk 56 pivoted at its centre to the head 25 and having a seriesof aper tures adapted to be moved into and out of registry with the apertures 27 The disk 56 has a handle 58 projecting through a slot 59 in the casing 10 whereby it may be adjusted, this slot being covered on the inside by the flange on the disk 56. The casing may be provided with a suitable filling opening closed by a plug 60, similar to the plug Having thus described 'my invention What I claim as new and desire to protect by Letters Patent of the -United [Statesis as follows:

1. A brush comprising a casing, bristles projecting therefrom, a follower in said casing, and a spring urging said follower forward, and a spring pressed braking device for retarding the forward movement of'said follower. I
